RustBox/CHANGELOG.md

# RustBox changelog

What changed in each RustBox release, written for the people who use and run it. Technical details are in the [documentation](docs/).

## 0.2.29

- An open message thread now updates automatically when a new message for that thread arrives via realtime events; reopening the thread is no longer required.

## 0.2.28

- Replying to a message you sent no longer addresses the reply back to yourself; RustBox chooses the other thread participant(s), including when aliases/identities are used.
- The mailbox toolbar now switches the message list between threaded and flat views. The compact icon-only control matches the message-selection button and changes its icon to reflect the active view. Threaded mode groups related messages by Message-ID/In-Reply-To/References, shows the thread size, and lets each thread expand or collapse; the reader follows the same persisted mailbox preference.
- Polish text decoding is more tolerant of legacy mail: RFC 2047 ISO-8859-2 subjects and common UTF-8/Windows-1252 or ISO-8859-2/Western-Latin mojibake are repaired in headers, bodies and cached message previews.

## 0.2.27

- Monochrome mode now creates a custom copy when editing a predefined interface style, just like direct colour changes.
- Wide message rows give more room to the subject and show the complete subject in a tooltip.
- Read/unread, flag and open actions no longer reserve hidden horizontal space; they appear to the left on hover.
- Shift-click message popups now open as a reader-only embedded view instead of briefly showing the full mailbox.
- Opening a message in a new window or tab now uses the same reader-only embedded view as the popup instead of the full mailbox/fullscreen layout.
- Adaptive HTML mail colours now derive light/dark mode from the actual reader background, so custom palettes stay readable even when their saved theme mode does not match their visual brightness.
- Mailbox storage is now clickable: folder properties can show IMAP-reported size in MB, and a storage dialog visualizes per-folder usage with progress bars.

## 0.2.26

- RustBox now has a license: the GNU AGPL v3, plus an optional paid commercial license for companies that prefer different terms. The About page explains both.
- The About page was redesigned: author, repository, license and a short note on the project's origin.
- RustBox is now developed independently of Oxi, the project its first version was forked from. The tools for synchronising with Oxi were removed.
- New documentation: a complete feature list with screenshots, a rewritten README and this user-friendly changelog.
- Settings notes in Polish now appear in Polish right after the page loads.
- Code cleanup with no change in behaviour.

## 0.2.25

- **Filters – Apply now:** a rule can be run on mail already in a folder, not only on new mail. "Check matches" shows how many messages a rule would affect; each rule in the list has its own "Apply now". Messages that cannot be checked with certainty are left untouched.
- **Filters – more options:**
  - exceptions ("except if…");
  - new conditions: To only, Cc only, message size, has attachment, high priority;
  - new actions: add a label, move to Trash.
- **Filters – easier to create:**
  - ready-made templates;
  - an offer to create a missing target folder;
  - "Always move messages from this sender…" in the message menu;
  - the quick filter can also be applied to messages already in the folder.
- Filter descriptions and confirmation buttons are translated.
- The message right-click menu is much shorter thanks to submenus and always fits the window, so Delete is always reachable.
- Fixed editing a predefined style mixing two styles together. Its layout can now be adjusted while it keeps its look, and only a colour change creates a custom copy (after asking).
- Fixed the "Soft" contrast option removing all borders.
- Fixed subfolders appearing in the wrong place in the folder list; they now appear directly under their parent folder.

## 0.2.24

- The **Style gradients** switch now works at every style depth, and every predefined style has optional gradients.
- New retro styles: Windows XP, Mac OS X Aqua, iOS 6, Windows 7, Frutiger Aero and BeOS.
- New **time-of-day** theme: light during the day, dark in the evening, at times you choose.
- Optional **account colour**, shown as a stripe at the top and a dot next to the address.
- A warning when your custom colours make text hard to read.
- Placeholder rows while a folder loads, and a smooth transition when the theme or style changes.
- Calendar: a **second reminder** per event (for example one day before) and default reminders for new events. All-day events are reminded at the start of the working day.
- The style list is grouped into categories and uses short names in English and Polish.
- Fixes:
  - a dark selection colour in the light theme;
  - subjects squeezed by previews in the message list;
  - the flagged-message marker;
  - the reader toolbar on narrow screens;
  - clearing an event reminder.

## 0.2.23

- **Style depth:** choose whether a predefined style changes only colours, also the layout, or the whole look ("immersive": shapes, fonts, panes, app bar and backdrop).
- A separate **Style gradients** switch.
- All styles were brought to a common standard with light and dark versions.
- 14 new styles: Dracula, Catppuccin, Solarized, Gruvbox, Tokyo Night, Rosé Pine, Everforest, Synthwave, Paper, Terminal, Aqua Glass, Linear, Material You and Retro 95.
- Database upgrade history was consolidated. Very old installations must first be upgraded with version 0.2.22.
- Fixed creating a new MySQL database.

## 0.2.22

- **Snooze:** hide a message until a chosen time and see all snoozed messages in one list.
- **Undo Send:** a few seconds to cancel a message after pressing Send (the length can be set by the administrator).

## 0.2.21

- Stronger protection against password guessing: repeated failures lock the mailbox or address for a growing time, before the mail server is even contacted.
- Login works reliably on installations without HTTPS, while secure cookies are still used whenever HTTPS is available.
- Memory protection when sending large attachments: oversized messages are rejected early and only a limited number are prepared at the same time.
- Ctrl/Cmd-click opens a message in a new tab, Shift-click in a small window.

## 0.2.20

- Messages without a date now get the date when they were received instead of landing at the end of the list.
- "Forward as attachment" attaches the original message exactly as received.
- Fixed recovery after an interrupted first synchronisation.

## 0.2.19

- HTML messages use all the available height in the reader and adapt when the window or layout changes.

## 0.2.18

- Better choice of the sender identity and signature for new messages.
- Undo and redo shortcuts in the editor.
- Better display of older and marketing HTML e-mails in light and dark themes.
- Moving a message no longer triggers a "new mail" notification.
- Quick account switcher in the top bar when several accounts are signed in, and combined notifications from selected accounts. The administrator can turn multi-account off.
- Signature editor improvements: equal-height fields, a source view and image insertion.
- Shift-click selects a range of messages, and the list has first/last page buttons.
- Images embedded in signatures are no longer shown as attachments.

## 0.2.16

- Optional adaptive colours for HTML e-mails, so they fit the dark or light theme.
- Paged message list (300 per page by default), with optional smooth loading or loading the whole folder.

## 0.2.15

- Fixed sticky bold/italic formatting in the signature editor.
- New messages with a signature get an empty line to type in above it, and a subtler separator.

## 0.2.14

- Compact single-line message rows when the list is wide (can be turned off).
- Per identity, choose whether the signature is visible while writing or added only when sending.
- Resizing panes no longer shows errors.

## 0.2.13

- Deleted attachments are always removed from storage, even after a temporary storage failure; cleanup is retried automatically.

## 0.2.12

- **Drafts:**
  - drafts from the Drafts folder, including ones created in other mail clients, open directly for editing;
  - new "Save draft" and "Delete draft" buttons;
  - saving a draft no longer causes a "new mail" notification.
- **Composer:**
  - images can be pasted, dragged into place, resized with handles, aligned and cropped;
  - added images are embedded in the text by default;
  - attachments can be embedded or inserted as links;
  - the address fields can be hidden to give the editor more room.
- Long recipient lists are collapsed in the reader.
- A "Load all" button next to "Load more" in the message list.

## 0.2.8
